摘要

在本研究中,我们提出了一个隐含的前瞻性系统性风险度量,该度量采用了看跌期权价格的信息,即系统性期权风险价值(SOVaR)。该指标比标准的基于股市的系统性风险指标(SRMs)更早地捕捉到金融领域系统性风险的积累阶段。非参数测试表明,与三个主要的基于股票市场的srm相比,我们的测量方法在2007-2009年全球金融危机的主要动荡事件中显示出更及时的预警信号(最多提前一个月)。此外,这一新指标还显示出对宏观经济衰退和未来衰退的显著预测能力。我们的结果对各种规格,金融部门的细分和控制文献中提出的其他主要风险措施都是稳健的。

Options-Based Systemic Risk, Financial Distress, and Macroeconomic Downturns
In this study, we propose an implied forward-looking measure for systemic risk that employs the information from put option prices, the Systemic Options Value-at-Risk (SOVaR). This new measure can capture the buildup stage of systemic risk in the financial sector earlier than the standard stock market-based systemic risk measures (SRMs). Non-parametric tests show that our measure exhibits more timely early warning signals (up to one month earlier) regarding the main turbulent events around the global financial crisis of 2007-2009 than the three main stock market-based SRMs. Moreover, this new measure also shows significant predictive power with respect to macroeconomic downturns as well as future recessions. Our results are robust to various specifications, breakdowns of financial sectors, and controlling for the other main risk measures proposed in the literature.
